9. Antenna footprint The recommended host PCB footprint is below.
6 copper pads all 1.1 x 0.9 (mm)
*CAD files of the antenna footprint are available at www.antenova-com. 10. Schematic
The circuit for the antenna and the matching components is below. The RF feed
connection and GND connections are critical to the function of the antenna, and must be followed as shown. This circuit can be used for the circuit capture of the host PCB.

11. Electrical Interface
11.1 Transmission Line
All transmission lines should be designed to have a characteristic impedance of 50Ω.
• The length of the transmission lines should be kept to a minimum • Any other parts of the RF system like transceivers, power amplifiers, etc, should also be designed to have an impedance of 50 Ω
Once the material for the PCB has been chosen (PCB thickness and dielectric constant), a coplanar transmission line can easily be designed using any of the commercial software packages for transmission line design. For the chosen PCB thickness, copper thickness and substrate dielectric constant, the program will calculate the appropriate transmission line width and gaps on either side of the track so the characteristic impedance of the co-planar transmission line is 50 Ω.
11.2 Matching Circuit
The antenna requires a matching circuit that must be optimized for each product. The matching circuit will require up to three components and the following pad layout should be designed into the device so the correct circuit can be installed.
The Pi matching network must be placed close to the antenna feed to ensure it is more effective in tuning the antenna.

12. Antenna Integration Guide
12.1 Antenna Placement Whichever the host PCB size used, the antenna should be placed into the PCB corner. Ideally Pin 1 should be closest to the PCB edge. The antenna requires a copper clearance on all PCB layers under the antenna section. The clear-out area is defined below. The clearance is minimal but must be followed for the antenna to function correctly.

For locations that are not on the corner the following clearances are required from each side of the antenna to GND.

12.2 Host PCB Layout The host PCB must ensure the footprint and clearance meets the antenna specification. An example of the PCB layout shows the antenna footprint with clearance. The antenna uses solder mask defined pads. Pin 2(GND) is shown directly connecting to the GND in the shortest route. The feed connects to the matching circuit close to the antenna.

13. MIMO Application example. Mutica works well in multiple antenna systems with simple integration to ensure good isolation between antennas. Below is an example of a 2 X MIMO system. Two antennas placed perpendicular to each other. Both antennas were optimised and matched for the same bands using the Antenova evaluation PCB. An S21 measurement between these antennas shows good isolation of <15dB minimum.

15. Soldering This antenna is suitable for lead free soldering. The reflow profile should be adjusted to suit the device, oven and solder paste, while observing the following conditions:
The maximum temperature should not exceed 240 ºC
However for lead free soldering, a maximum temperature of 255 ºC for no more than 20 seconds is permitted.
The antenna should not be exposed to temperatures exceeding 120 ºC more than 3 times during the soldering process.
16. Hazardous Material Regulation Conformance The antenna has been tested to conform to RoHS requirements. A certificate of conformance is available from Antenova’s website.
17. Packaging
Shelf life 24 Months
Storage place Away from corrosive gas and direct sunlight
Packaging Reels should be stored in unopened sealed manufacturer’s plastic packaging.
Note: Storage of open reels of antennas is not recommended due to possible oxidization
of pads on antennas. If short term storage is necessary, then it is highly recommended that the bag containing the antenna reel is re-sealed and stored in like storage conditions
as in above table.
The shelf life of the antenna is 2 years provided the factory seal on the package has not been broken.
